Sago palm is one of Genus Metroxylon belonging to Family Palmae, that accumulates a huge amount of starch in its stem.As invaluable resouces of starchy food, sago palm could be an important role in respect to possible food shortage in the world in future. Sago palm is a tropical plant which not only grows in the dry lands but also grows with high adaption to low-lying wetlands such as fresh water swamp, peat swamp or brakish water. The origin of sago palm is believed to be the area extending from Moluccas, and Papua of Indonesia to New Guinea. However, the attention to explore spread and potential of sago stock has not been done adequately in Papua. The Objective of this study is to develop spatial statistics method for mapping and estimating sago stock in Inanwatan District, Sorong Selatan Regency, West Papua. Area frame sampling of square segment method is applied for estimating sago stock, which involves some stages, i.e., (1) Stratification of study area by using high resolution of satellite data, (2) Design of sample frame survey, (3) Field survey for ground truthing, and (4) Data analysis. The Results show that the total of study area is 13,315 ha consisted of 2,892 ha non-sago forest and 10.423 ha sago forest. Sago forest is divided into 3 strata, namely low density, medium density, and high density, which has area of 630 ha, 392 ha, and 9,401 ha respectively. The population of ripe sago palm in low density, medium density, and high density are 22.680 stands, 32.928 stands, and 549.018 stands equal to 4.930 tons, 7.226 tons, and 109.044 tons of sago starch, respectively. So that, the total sago stock in the whole study area is 121.200 tons of sago starch.
